David,

Unless the servo you use has a capacity of torque and servo gear strength which exceeds the theoretical maximum load that could be placed on it by a max speed max g load manuever, it will fail and quite possibly cause flutter in that instance. Hence your suggestion of using 9411 servo's instead of the smaller, less powerful, 3421, in fact accomplishes no more than your beginning statement "Sure some guys, probably most guys, will get away with it but not every" There is no system, currently that can feasibly be installed in our models which will give 100% protection against exceeding design limits. The 3421's work in most cases, as has been proven in the field and thru testing, but not all. Your suggestion will work in most cases, maybe even more cases, but not all. There's not a plane thats been built, that some fool pilot can't break! Given half a chance.

I rest my case.
